Second Hand BMW 3 Series EGR Valve

EGR valves exist on the 3 Series, but only on diesel engines — petrol variants of the 3 Series do not use an EGR valve in the same way, so if you drive a petrol model this is unlikely to be the part you need. On diesel engines (the 318d, 320d, 325d, 330d and so on), the EGR valve is a standard emissions component that recirculates exhaust gases to reduce NOx output. If you're unsure whether your engine is diesel or which engine code you have, check your V5C or search your registration on the DVLA website before requesting quotes.

Almost certainly not — the E90 generation (2005–2012, facelift 2008) and the F30 generation (2012–2019, facelift 2015) use different engine families, different emissions standards, and different EGR valve designs. The engine code is the critical detail here: even where two engines appear similar in displacement, the emissions hardware changed significantly between these generations as BMW moved through Euro 4, Euro 5, and Euro 6 compliance. Always give the breaker your exact engine code (found on your V5C or stamped on the engine block) and confirm against it before buying.

No — trim level has no bearing on EGR valve fitment on the 3 Series. Whether your car is an SE, Sport, M Sport, or xDrive variant, the EGR valve is determined entirely by the engine code and the emissions era the engine was built to. An M Sport badge changes suspension tuning, bodywork, and interior — not the emissions hardware. Focus your search on matching the engine code rather than the trim name.

Quite possibly, since both sit within the F30 generation (2012–2019) and the 2014 facelift did not fundamentally change the N47 engine family used in the 320d. However, BMW introduced running production changes and different engine code suffixes across these years, so the safest approach is to confirm the full engine code on both cars with the breaker before purchasing. The breaker will be able to cross-reference the part number against your registration to check compatibility.

Yes — this is one of the most important fitment boundaries for EGR valves on the 3 Series diesel range. Euro 6 engines (broadly from 2014–2015 onwards on the 3 Series, when the B47 engine began replacing the N47) have revised emissions hardware including updated EGR systems designed to meet stricter NOx limits. A valve from a Euro 5 N47-engined car is not a straight swap onto a Euro 6 B47-engined car, and fitting the wrong unit could cause running problems or an MOT emissions failure. Confirm your engine code and Euro standard with the breaker so they can source the correct valve.

It depends entirely on whether the donor car shares the same engine code as yours — BMW used the same engine families (such as the N47 or B47) across multiple models, so a cross-model swap is sometimes possible where the codes match exactly. However, ancillary pipework, sensor connectors, and mounting positions can differ even between engines of the same family, so this is not something to assume without verification. Give the breaker both registrations and your 3 Series engine code, and let them confirm against the part number before you commit.
